Hey, and welcome to the world of RX-7's. I will be the polite one and tell you to use the search button.

A good shutter valve thread:

Just to get you started

Also, Post up some pics!

The shutter valve just keeps the engine from bucking when you slow down gradually.Its part of the carb/intake and its pretty common to see them frozen/sloppy/or just plain plugged off.
If the car runs fine and doesnt buck or kick when you coast or cruise around 20-30 MPH,then you can just leave it be.Or look around the junkyards or this site/Ebay for a replacement.Its pretty easy to fix,although finding one that's still in good shape can be tough.

So that explains the bucking I get around 2500 RPM

Far as if you decide to replace it just post a WTB ad in the 1st gen classified parts section.
